With more experimentation, I see this same behavior even in the exact
sample code, under IE or FF.
To see:
Hide col0, then show
Hide col1, then show ... you will not see it!
Hide col1, then show ... now you will
This can be seen even in the associated AJAX API playground, by
modifying it to say:
t1 = new google.visualization.AnnotatedTimeLine
(document.getElementById('visualization'));
t1.draw(response.getDataTable(), {'displayAnnotations': true});
t1.hideDataColumns(0);
t1.showDataColumns(0);
t1.hideDataColumns(1);
t1.showDataColumns(1);
Help! Am I misunderstanding the way this is supposed to work?
